Adding boundary terms to Anderson localized Hamiltonians leads to unbounded growth of entanglement
Yichen Huang
It is well known that in Anderson localized systems, starting from a random product state the entanglement entropy remains bounded at all times. However, we show that adding a sing…
Locally accurate matrix product approximation to thermal states
Yichen Huang
In one-dimensional quantum systems with short-range interactions, a set of leading numerical methods is based on matrix product states, whose bond dimension determines the amount o…
Extensive entropy from unitary evolution
Yichen Huang
In quantum many-body systems, a Hamiltonian is called an ``extensive entropy generator'' if starting from a random product state the entanglement entropy obeys a volume law at long…
Finite-size scaling analysis of eigenstate thermalization
Yichen Huang
We study the fluctuations of eigenstate expectation values in a microcanonical ensemble. Assuming the eigenstate thermalization hypothesis, an analytical formula for the finite-siz…
Entanglement Dynamics From Random Product States: Deviation From Maximal Entanglement
Yichen Huang
We study the entanglement dynamics of quantum many-body systems and prove the following: (I) For any geometrically local Hamiltonian on a lattice, starting from a random product st…
